Meghan and Harry made the visit to see their work supporting young people through creative training in radio and broadcasting, and to learn more about their model of using music, radio and media for social impact.

It is their first official trip out as a couple in London, although they were spotted in the city many times while they were dating. It is their second official engagement together, the first being a visit to the Terrence Higgins Trust World Aids Day fair in Nottingham.

An onlooker spotted them on a BA flight to Nice, and they were reported to have taken a helicopter to Monte Carlo.

A source told the Mail the couple were being guarded by France's elite Service de la Protection, the police unit responsible for the protection of foreign dignitaries.

While their reasons for heading to France were not revealed, it could be as simple as the weather, with the south of France enjoying significantly warmer temperatures than England at this time of year.

Wedding planning is well under way for the couple, but it has been revealed their first choice of venue was vetoed by the Palace.

Their first choice was the stunning Frogmore House, the site of another royal wedding in recent years.

The house, located within Home Park next to Windsor Castle, is a large white stately home with an air of grandeur.

Built in the 1680s, the home is over 300 years old. However the building has a fashionable 1920s feel to it.
